HMRC recently confirmed its selection of SAP to lead a comprehensive upgrade of the UK’s tax technology infrastructure. Central to this plan is the migration of the Enterprise Tax Management Platform (ETMP) to a cloud-based system.
The ETMP underpins the collection and administration of over £800 billion in tax revenues annually and supports more than 45 different tax regimes. The decision forms part of HMRC's long-term strategy to simplify its technology landscape and deliver improved services.
Upgrading one of the country's most critical public financial systems underscores the scale and importance of the transformation within the UK’s government digital agenda.
Role of SAP in the Overhaul
Under the modernisation programme, SAP will deploy its suite of cloud technologies, including SAP S/4HANA Cloud and the SAP Business Technology Platform, supported by the UK Sovereign Cloud. This transition is designed to enhance the resilience and security of the nation’s tax systems.
SAP's UK Sovereign Cloud ensures that tax data remains within the UK’s jurisdiction, adhering to national data residency, security, and compliance requirements.
Leila Romane, Managing Director UKI at SAP, emphasised that the upgrade will help 'strengthen the resilience, security and sustainability of critical national infrastructure.'
Objectives of the Cloud Migration
HMRC is seeking to replace complex and fragmented legacy systems with the new cloud-based platform. This shift is intended to provide HMRC employees with improved access to real-time analytical data and more reliable reporting tools, thereby supporting better decision-making.
According to HMRC, the user experience for both staff and taxpayers will be significantly enhanced. The new platform promises greater transparency, improved responsiveness, and more intuitive digital interfaces in managing tax affairs.
Enhancing Data Security and Compliance
One of the central priorities in the migration is ensuring robust security and regulatory compliance. The implementation of the UK Sovereign Cloud is intended to address national concerns about data privacy, with all taxpayer information being stored and managed within the UK.
The migration also aligns with the government’s increased focus on digital resilience and sustainability. SAP noted that the approach supports the secure delivery of public services at scale, factoring in the growing reliance on digital tools in public administration.
Impact on Taxpayers and Employees
The move to the cloud will affect a broad user base, with tens of thousands of HMRC staff relying on ETMP daily to process and manage tax records. Improved analytics and user interfaces are expected to increase confidence in real-time data and reporting.
For taxpayers, HMRC stated that the changes will result in a more transparent and responsive experience. The enhanced system aims to streamline interactions, making it easier for individuals and businesses to understand and fulfil their tax obligations.
Aligning with Government AI Ambitions
Beyond immediate operational improvements, the HMRC-SAP partnership is set to advance the government’s wider ambitions for AI and digital innovation in public services. The collaboration will explore new AI capabilities to speed up insights, automate processes, and aid decision-making.
SAP has indicated that this initiative will contribute toward developing AI-driven tools tailored to improve tax administration and customer experiences, in line with official strategies to modernise public sector functions through technology.
Final Summary
HMRC’s alliance with SAP marks a pivotal stage in the modernisation of the UK tax administration. Through this migration to the cloud, HMRC seeks to address operational challenges, enhance security, and pave the way for further digital innovation, including AI integration.
The project highlights an ongoing commitment within UK government departments to future-proof critical public services and improve outcomes for staff and citizens alike.
